Point to Point Wireless Internet

I am wanting some info on setting up a point to point system to share
wireless internet from one building to another (Around 500 ft apart).

The building have no obsticles between each other as is mostly gravel
driveway. I am thinking of ordering for a wireless G setup.

2-YSC-HG2415Y (Yagi Antennas) one for sending and one for receiving
http://www.hyperlinktech.com/web/hg2415y.php

1 N-male to RP-SMA (for the wireless card in the computer)
1 N-male to 90° RP-SMA (For the router)

This same equipment will work for "pre-N", But do I need three yagi antenas
per router, as most of the pre-N router have three anteanas coming out of
them.

If I would like to broadcast my internet to two different locations can I
use a splitter of some sort and feed the signal to two yagi antennas from my
router


What sort of cable do I need to run from the yagi antena to the router and
wireless card , I have read that it should be a LMR400 is there other types
of cable I can use??.

Thanks for any help,

Bryon

Using outside rain proof boxes, use a Linksys WRT54G for the access point
and Linksys WAP54G in client mode for the remote sites. With a clear shot,
that will work a good 1,000 feet, even in the G mode. If not, drop it down
to the B mode.

Will using rain proof boxes ouside not hamper signal at all. That is why I
figured the Yagi antenna would be a good choice. It was external to the box.

The yagis will gain you the best usable signal and i would stick with that
idea, however I would depending on how far you have to run the cable from
the router and or computers to the antenna you might be better off to save
the loss of all that coax and put the Router and AP's outside with only
short jumpers to the yagis
I think you'd be better off with a wireless access point and yagi and your
remote machine hooked to it..

How long is too long when running cable from the yagi to the router or
access point. Do you need to use the LMR 400 cable or is there a different
cable that I could use. Could I run a lower grade of cable and put some sort
of signal booster inline.

No, the lower grade of cable will be more lossy. Adding an amplifier to
increase the signal gain will also increase noise. The cheapest and most
effective solution is to take advantage of the passive gain of an high gain
antenna, followed by low loss cable. Use LMR 400 or better, nothing less.

Using LMR 400 or better how long would a max cable length be?? Are the
linksys routers, better than D-link for signal strength.

I would use Linksys routers or the Buffalo equiv. Simply because you can use
third party firmware which will allow you more configurability on the LAN
such as being able to increase your TX power from 26mW to 250mW. I would run
it around 100mW unless you can run less and keep the link speeds you want.
As far as the cable goes that all depends on what antennas you use and how
much gain they provide. Then check the specs on on LMR400 and see how much
loss there will be over the amount of footage you will need to reach your
antenna. If you wont end up with at least 3 to 6db of gain (hopefully you'll
have more) than I would look at moving the radio's closer to the antennas..
One other thing to think about is CAT5e is MUCH cheaper than LMR400..

Happy linking.

Using the Linksys WRT54G for the access point and Linksys WAP54G in client
mode for the remote sites.
Are there certain Firmware revs that I should be looking for?? Is there any
benifit to looking at the Pre N stuff.

not unless you need the speeds IMHO.
As far as firmware goes, none that i know of as far as linksys goes.. there
is always DD-WRT if thats what you mean
